Abstract

This report takes another look at protected/permissive (p/p) left turns at signalized intersections using a new display, the flashing yellow arrow (FYA). A National Cooperative Highway Research Project (NCHRP 3-54) was formed to study the effectiveness of several different p/p displays that are used across the United States. Jackson County Roads applied and the Federal Highway Administration (FHWA) approved our request to study the FYA. The FYA is compared to the circular green display (Doghouse) at a signalized intersection in Jackson County, Oregon. Also analyzed are several intersections converted from protected only left turn operation to p/p using the FYA. Benefit/cost ratios, citizen comments and observations are used to compare the FYA display with existing phasing and control devices.
